From the announcement:
We know how to make books. I like to joke that we can fall out of a bed and stand up with a book in our hands. However, with Leviathans we tackled a slew of new manufacturing items we’d never dealt with before. It would have been bad enough to have even one of those additional elements on the table, but we went ahead and tried to tackle a dozen at a time.
Where does that leave us since Leviathans published late last year? Well, it pretty much sold right out when it published. Which is fantastic! However, the way in which we packaged the game makes it unsustainable (again, that learning curve). As such, we need to find a new way to repackage the line so it can sustain itself.
We are currently looking at reshaping the entire line into something similar to how Sails of Glory/Wings of Glory (as well as Star Wars: X-Wing or Star Trek: Attack Wing) package and release their games and miniatures. This would in effect be a re-launch for the game.
